These are high quality machined steel mandrels. Because the mandrels are made of hardened steel they are much stiffer then standard tube pins. The mandrels fit all 3 diameters of tubes that we carry. They are intended to be used with a feed through/clamp down vise or vise tool. We carry the straight mandrels in 3 diameters 0.8mm. (fits 1.8mm tubes), 1.6mm (fits 3mm tubes) and 2.5mm (fits 4.1mm tubes). The angled mandrels are available in 1.6mm and 2.5mm. Length specs: 6″ long straight mandrels or 3″ long mandrels with a 90 degree end. Some tiers like the no-clutter straight end and some like the 90 degree end to facilitate mandrel removal.
Available as singles, or packages of two angled mandrels or three straight mandrels.
